SPECIFICATION forming part of Letters'Patent No. 763,541, dated June 28,1904.

Application filed May 22, 1903. Serial No. 158,308. (No model.)

To (bl/Z whom it may concern.-

Be it known that I, QUINGE CRANE, a citizen of the United States, and aresident of San Diego, in the county of San Diego and State ofCalifornia, have invented a new and Improved Range, of which thefollowing is a full, clear, and exact description.

This invention relates particularly to improvements in acombined range,baking-oven, and serving-table, an object being to provide a device ofthis character that shall be accessible from all sides and that willoccupy but comparatively little space, adapting it for use in hotels orrestaurants.

I will describe a range embodying my invention and then point out thenovel features in the appended claims.

Reference is to be had to the accompanying drawings, forminga part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the figures.

Figure 1 is a section on the line 1 1 of Fig. 2 of a range embodying myinvention. Fig. 2 is a section on the line 2 2 of Fig. 1. Fig. 3 is asection on the line .3 30f Fig. 1, and Fig. 4 is a section on the line 44 of Fig. 1 and on an enlarged scale. h

Referring to the drawings, 5 designates a casing of sheet metalsupported on standards 6, and connected to these standards are shelves7, on which material to be kept warm may be placed. The casing 5 isdivided longitudinally by a partition 8, having openings at intervals,the said openings being controlled by dampers 9 10, which haveoperating-rods 11 extended outward through a wall of the easing. Whenthese dampers 9 10 are closed, it is obvious that the partition ispractically continuous, and two fines and heating-chambers 12 13 areprovided. The partition, however, does not extend entirely to the end ofthe easing, and therefore one flue communicates with the other, asclearly indicated in Fig. 2.

At each side of the partition the casing is provided with shallow ovens,here shown in the form of drawers 14, which are arranged with a spacebetween their upper sides and the top of the casing and with a spacebelow their lower sides and the bottom of the casing, so that productsof combustion may pass above and under the ovens when desired. Theseshallow ovens 14 are designed for the making of toast, baking of pies,biscuits, or any rapid baking. I

Communicating with one end of the flue 12 is a fire-box 15, and from theash-pit or from a point below the grate 16 an air-inlet flue 17 extendsalong the under side of the casing 5. The front of the fire-box will ofcourse be provided with a suitable door or doors.

Arranged below each heating-chamber 12 and extended transversely of thecasing is a damper 18, and similar dampers 19 are arranged above theovens. By closing the upper dampers all of the heat may be caused topass underneath the ovens, and obviously by closing the lower dampersand opening the upper ones the heat will pass over the ovens, whileopening both dampers theheat will pass both above and below said ovens,and, further, by closing any pair ofupper and lower dampers and byopening one of the dampers 9 or 10 the heat will be short-circuited orcut off from a portion of the chamber. At the opposite side of thefire-box to that of the ovens 14 is a large baking-oven 20, arranged ina brick or other suitable shell 21 and spaced therefrom, so there is afree circulation of heat around the oven, the products of combustionfinally passing out through the uptake 22. Spaces 23 between the oven 20and the shell 21 communicate with one of the flues 18, and thecommunication is controlled by a damper 24, and a damper 25 is arrangedbetween the fire-box and said flue 13.

In the operation when all of the dampers excepting the dampers 9, 10,and 25 are open the products of combustion will pass through the fine12, back through the flue 13, and then around the oven 20 and outthrough the uptake 22. Should it be desired to use the oven 20 alone,the dampers 18 and 19 nearest the fire-box are to be closedin both fiuesand the damper 25 opened.

The top of the casing 5 forms a table on which material to be served maybe placed, and to prevent the material from becoming excessively heatedI provide pads 26, of nonconducting material-such as asbestos,preferably sti'fiened by a core 27, of sheet metal.

To permit the passage of air underneath the pads and prevent excessiveheating, I mount the pads on short legs 28, and these pads may be movedto any part of the casing or removed therefrom, if not desired for use.

A range made in accordance with my .invention will result in economy ofspace, time, and labor, also fuel, as floor-space is saved by discardingthe ordinary serving-table, the work being done directly from the range,and labor is saved by removing the necessity of walking from a range toa table, or vice versa, and also in allowing waiters to dish up food,not depending entirely on cooks for all the serving. Fuel is saved, ascomplete control of heat is managed by a series of dampers in the fines,and a further economy in fuel results from the heating of the air inpassing through the inlet 17 to the fire-box.

Having thus described my in vention,I claim as new and desire to secureby Letters Patent 1. A range, comprising a casing, a partition extendedlongitudinally therein and having openings at intervals, dampers forsaid openings, sliding ovens at each side of the partition, the saidovens being spaced from the top and bottom of the casing, a fire-box atone end of the casing, and dampers above and below said ovens at thesides toward the fire-box.

2. A range comprising a casing, a longitudinal partition in the casinghaving openings at intervals, dampers for said openings, a firebox atone end of the casing, an air-inlet flue leading underneath the casingand communieating with the fire-box, sliding ovens in the casing at eachside of the partition, the said sliding ovens being spaced from the topand bottom of the casing, dampers extended tra-nsversely of the casingabove and below said ovens at the sides toward the fire-box, and abaking-oven communicating with the casing.

3. A range comprising a casing, a partition extended longitudinallytherein and having openings at intervals, dampers for said openings,ovens at each side of the partition, the said ovens being spaced fromthe top and bottom of the casing, a fire-box at one end of the casing,and dampers above and below said ovens at the sides toward the fire-box.

4. A range comprising a casing having a longitudinal partition providedwith openings at intervals, dampers for said openings, the saidpartition forming two heating chambers and fines, a large even havingcommunication withone of the flues, a damper for controlling saidcommunication, a damperfor controlling communication between thefire-box and the flue communicating with said large oven, sliding ovensarranged in the casing at opposite sides of the partition, and means forcontrolling the passage of products of combustion along said ovens.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
